A second-degree polymonial in x is given by the expression ax2+bx+c, where a, b, and c are known numbers and a is not equal to 0. What a C function named polyTwo (a, b, c, x) that computers and returns the value of a second-degree polynomial for any passed values of a, b, c, and x. Make sure your function is called from main (). Have main() input values of a, b, c, and x, call function polytwo() to get and display the value retuned. Test the function by passing various data to it.

Perform the following tasks: a. create a class named testclass that holds a single private integer field and a public constructor. the only statement in the constructor is one that displays the message “constructing”. write a main()function that instantiates one object of the testclass. save the file as testclass. cpp in the chapter 08 folder. run the program and observe the results. b. write another main()function that instantiates an array of 10 testclass objects. save the file as test class array. c . run this program and observe the results.
